I ran a stranger's SaaS idea through real market data — here's what I found
Someone shared they were building ReviewLinker — a tool for Amazon authors to fix broken international review links.
I ran it through Valify and the data said something uncomfortable:
BookLinker and Books2Read already solve this for free. Zero search volume. No funded competitors.
Score: 33/100 — Red.
But the data also surfaced one viable pivot: review conversion analytics inside KDP dashboards. That gap exists and free tools can't fill it.
This is exactly why I built Valify — not to kill ideas, but to redirect them before founders waste months building the wrong thing.

Hard data is the only cure for founder bias. It’s much cheaper to kill a bad idea in a day than to spend six months building a ghost town. Better an uncomfortable truth now than a $0 bank account later.
